Decided to take the GN out today so I changed the oil with a WIX filter and Mobile 1 10w 30.
I left on an 80 mile 1 way trip to my home town. All went well until I stopped when I got there to get fuel. Once I fueled up and left station the motor started to make noise, I would describe it like a diesel sound. At idle the motor sounds perfect. Under a load it made noise??
I went 4 miles easy to a bar and had lunch. After eating I left and the noise wasn't as bad. Thought Maybe I got bad gas so I added a can of seafoam. Drove across town and let my brother in law listen to it. He builds high end stock car motors and his opinion is a rod bearing.
My oil pressure has never been stellar in this car but I have read several threads which said a lot of guys have had the same pressure as me so I never bothered with it.
Not sure what happened but I drove the car home 80 miles and it ran fine but under a light load I hear a diesel sound. The only other time I have heard the same sound was after a pass at the strip on the return road. It didn't really concern me because it went away, I kind of figured it may be exhaust rattle etc.
If anyone has any ideas my ears are open. I will check TQ bolts in the morning but I'm doubting that at this point. We just put a new converter in last fall.
Too bad because this motor is supposed to have under 4000 miles and it running pretty good.
